Apparatus for retrofit of auxiliary serial communication port(s) in a slot accounting system

1. A serial network switch for rerouting serial communications from a slot accounting system directed to a slot machine interface board (“SMIB”) within a cabinet of a slot machine, the serial network switch comprising: an input port for communicably coupling to, and receiving serial communications from, the slot accounting system; a SMIB port for communicably coupling to the SMIB; a processor coupled to the input port and the SMIB port; and a network module coupled to the processor and communicably coupled to a server; wherein: the processor is configured to transmit at least one serial communication received from the slot accounting system via the input port to the server via the network module.

2. The serial network switch of claim 1 , wherein the network module comprises one of a Wi-Fi module or an Ethernet module.

3. The serial network switch of claim 1 , wherein the server is one of a promotion server or a player tracking server.

4. The serial network switch of claim 1 , further comprising: an auxiliary port for communicably coupling to a bill validator within the cabinet; wherein the processor is configured to route serial communications received via the input port from the slot accounting system to one of the SMIB or the bill validator based on data extracted by the processor from the received serial communications.

5. The serial network switch of claim 4 , wherein the data extracted from the received serial communications comprises an endpoint address.

6. The serial network switch of claim 1 , wherein the processor is configured to authenticate communications from the slot accounting system.

7. The serial network switch of claim 1 , wherein the received serial communications are formatted according to the Slot Accounting System protocol.
